Albert Barnes Commentary 1 Samuel 12:2

"And now, behold, the king walketh before you; and I am old and grayheaded; and, behold, my sons are with you: and I have walked before you from my youth unto this day." — 1 Samuel 12:2 (ASV)

My sons are with you - Possibly, however, a tinge of humiliation at the rejection of himself and his family, mixed with a desire to recommend his sons to the nation's favor and goodwill, is at the bottom of this mention of them.
